14 Claims.

This invention relates to a jogging machine for straightening sheets ina stack with the edges thereof in registry with each other, and has forits principal object to provide a machine of this character which is ofsimple construction and efficiently brings the guide edges of the sheetsinto precise registry.

Other objects of the invention are to provide a jogging machine with avibratory table mounted on its supporting frame so that the vibrationsare not transmitted through the frame to the building structure in whichthe machine is housed; to provide a machine wherein the mechanicalconnections between the actuator and the jogging table are constructedfor silent operation and to further reduce objectionable transmission ofthe vibrating forces; and to provide a jogging table particularlyadapted for jogging light weight stock such as india, manifold tissue,carbon and onion-skin papers without frilling or curling of the edges.

It is a further object of the invention to provide a jogging tablecapable of simultaneously jogging a plurality of piles of sheets.

Referring more in detail to the drawings:

1 designates a jogging machine constructed in accordance with thepresent invention, and which includes a relatively rigid base havingsuflicient weight in the body thereof so 'as to provide a stable supportfor the machine, and so that the inertia thereof is sufiiciently greatto avoid transmission of vibrations to the building in which the machineis housed.

The base of the machine includes a plate-like body 2, having a footingflange 3 whereby the base is adapted for stable support on a floor. Thecenter of the plate portion is preferably provided with an opening 4,and extending transversely thereof is an axle shaft 5 carrying wheels 6and 1. The ends of the axle are carried. in bearing brackets 8 adaptedfor vertical movement within guide sockets 9 upon manipulation ofjack-screws l0 so that the base may be moved relatively to the wheels 6and I to raise the base from the floor and facilitate movement thereofwhen the machine is to be moved from one location to another.

Extending upwardly from the base are sockets H and I2, rigidly receivingthe ends of posts l3 and [4 for supporting the jogging table, laterdescribed. The upper ends of the posts are preferably flat and adaptedto be clamped to a supporting frame l5 by clamp screws IS.

The frame I5 is of substantially rectangular form and includes a top I!having a substantially rigid rim I8 depending therefrom, whereby theframe is of substantially rigid construction and free from any fiexureincidental to vibration of the jogging table I9. The opposite sides ofthe frame are provided, substantially on the longitudinal median linethereof, with internally threaded sockets which register with openings2| in the flat ends of the posts to pass threaded shanks 22 of theclamping screws IS. The clamping screws have head portions 23 providedwith collars 24 to engage the outer faces 25 of the posts and to causeclamping engagement of the inner faces 26 of the posts with the sidefaces 21 of the frame when the shanks 22 are threaded The heads 23 ofthe clamping screws are provided with levers 28 whereby the screws maybe readily manipulated to clamp the supporting frame at a selected anglebetween the posts, as clearly shown in Fig. 2.

The jogging table l9 includes a rectangular frame 29 having side bars 30connected by end rails 3|, are parallel bars 33 and 34 spaced apart I adistance slightly greater than the width of the supporting frame andwhich extend parallel with the sides thereof so that one of the corners35 of the jogging table is positioned so a bisector thereof extends atsubstantially right angles to the tilting axis of the supporting frame,as shown min Fig. 6. The frame is provided with a top board 38 that isrigidly secured thereto by suitable fastening devices as indicated at31. Secured to u the side and end rails forming the corner 35, and Yprojecting outwardly therefrom, are brackets 38 {and 39 having flatfaces 48 and ll respectively registering with the ends of the supportingframe as shown in Fig. 6. Carried by the diagonal bar 34 is a similarbracket 42 located in alignment with the bracket 38 at the oppositecorner of 'iothe supporting frame. The corner at the opposite end of thesupporting frame is cut away, as indicated at 43 so as not to projectbeyond the side wall 38. Extending from the table, adjacent the junctureof the diagonal 34 and the intermediate rail 32, is a similar bracket 44having a side face 45 thereof registering with the side face of asimilar bracket 48 projecting from the side of the supporting frame.

Connected with the side faces of the brackets.

thus described are spring leaves 41, spacingly retaining the table inspaced parallel relation with the supporting frame, the upper ends ofthe -..leaves being secured to the respective brackets by fasteningdevices 48, having the shanks 89 thereof extending through clampingblocks 58, through openings 5| in the leaves, and into threaded sockets52 of the brackets, whereby, when the fastening devices are tightened,the heads rigidly clamp the blocks against the spring leaves and thespring leaves against the flat faces of the brackets. The lower ends ofthe spring leaves are secured to the frame by similar fastening devices53. The table is thus resiliently supported by the spring leaves, andsince the spring leaves are arranged in planes extending transversely ofthe pivotal axis of the supporting frame, the table is adapted tovibrate with respect to the supporting frame with the bisector of thecorner 35 shift:

. ing relatively to the tilting axis.

Carried by the side and end rails forming the corner 35 are a pluralityof guide stakes 54 for engaging the guide edges of the sheets to bejogged, as later described. Depending from the sides of the supportingframe and offset from the bisector of the corner 35 is a parallel shaft55, having its ends suitably joumalled in bearing brackets 58 and 51depending from opposite sides of the supporting frame. Mounted on theshaft is a pulley 58 that is driven by a belt 59 operating over thedrive pulley 68 of a motor 8| which is suspended below the supportingframe, as shown in Fig. 3. Also fixed on the shaft, adjacent thesupporting brackets, preferably by keys 62, are eccentrics 83journalling eccentric straps 84 on needle bearings 85. Carried by thesides of the supporting frame are stub shafts 86, the stub shafts beingpreferably provided with, reduced tapered shanks 81 engaged in taperedsockets 88 of the frame and which are drawn tightly therein by nuts 89mounted on threaded ends 18 of the tapered shanks. Carried on the stubshafts by needle bearings II are rocker arms 12 and l3 having weightedends 14 and upwardly extending arms I5 offset with respect to the axisof the stub shafts as shown in Fig. '7. The weighted ends 14 are notchedsubstantially in alignment with the horizontal plane extending throughthe axis of the rotating shaft to form seating faces 16 cooperating withsimilar faces 11 on lugs 18 of the eccentric straps to attach springleaf connectors 19, the leaf connectors being rigidly secured to therespective faces by fastening devices 88 having the threaded shanksthereof extending through clamping blocks 8|, through the ends of theleaves, and into threaded sockets 82 as clearly shown in Fig. '7.

Secured to the under side of the jogging table, in alignment with therocker arms, are brackets 83 having the lower faces 84 thereofsubstantially registering with the upper faces 85 of the arms 15 to beconnected by spring leaves 88, the spring leaves 88 being retained byclamping plates 81 and 88, having flanges 89 engaging over the, ends ofthe leaves and lapping the opposite faces of the brackets 83 and arms 15respectively. The clamping plates are rigidly secured in position byfastening devices such as cap-screws 98, having their threaded shanksextending through openings in the plates, through registering openingsin the ends of the spring leaves and into threaded sockets as shown inFig. 7.

Rotation of the eccentrics incidental to actuation of the shaftoscillates the rocker arms and effects vibration of the jogging table,whereby sheets placed in a stack on the table, as indicated in Fig. 1,are caused to shift against the stakesat one side when the table movesin one direction, and then against edges of the stakes at the other sidewhen the table moves in the opposite direction, resulting in alignmentof the stake-engaging edges of the sheet.

The motor for actuating the eccentric shaft is energized through aswitch SI mounted on the base and having an operative connection througha link 92 with a foot treadle 83.

In order to prevent the guide edges of the sheets from curling andclimbing up the stakes, selected stakes are provided with hold-downclips as shown in Fig. 9, which clips float freely on the stakes andbear upon the margins of the sheets as the sheets settle thereunderincidental to vibration of the table. The clips are preferably formed ofa single piece of wire bent at spaced points 94 and 95 intermediate theends thereof to form a cross bar and vertical leg portions 96 and 91,the lower ends of which are bent on an angle, as at 98 and 99, to formthroats or guides whereby an applied sheet settles under the arms I88and IM which bear on the sheet. The arms are of suflicient length toextend to the rear of the stakes and terminate in inwardly directedportions I82 and I83 connected with vertical portions I84 and I85, theends of which are bent to form a loop I88 loosely engaging the stakewhereby the portion I88 and IM bear upon the sheet with the projectingportion, including the legs 98 and 81, acting as a weight. As shown inFig. 10, the stakes are inclined outwardly at a slight angle relativelyto the table so as to avoid and character of the stock being jogged.This is effected by lessening the clamps and tilting the frame, afterwhich the clamps are retightened. The operator then places his foot onthe treadle to effect energization of the motor for rotating theeccentric shaft. Rotation of the shaft v-ibrates the table through therocker arms and spring leaf connections so that the table moves relativeto the frame on the spring leaf supports 41, the table oscillating withsufficient rapidity so that when a sheet is placed on the table it willsettle into the angle-shaped pockets formed by the corner 35 with theside edges engaging the stakes. As succeeding sheets of paper are fedonto the table, the guide edges thereof will be automatically moved toregistry with the edges of the first sheet to produce a stack with allof the edges in precise registry. The weight portion of the rocker armsbalance the moving parts of the table so as to dampen vibrations tendingto cause the entire machine to vibrate, thereby avoiding the objectionand noise incidental to jogging devices with which I am familiar.

From the foregoing it is obvious that I have provided a jogging devicewhich is of simple construction and which efficiently registers theedges of loose sheets.

Fig. 11 shows a different stake arrangement. In this arrangement twosets of stakes I01 and I08 are mounted on the table so that two piles ofsheets may be jogged simultaneously. Otherwise the machine isconstructed in the same manner as the one above described.
